Hi there! My name is*****'d be happy to help you with this. A replacement cable for you Kodak easyshare c340 can be found fairly easily online. I will post a link to the cable that you need on amazon below. If you would prefer to purchase locally, I recommend checking with Best Buy or a local camera shop. There is a good chance that either will have the cord that you need.
If the information that I have provided has been helpful, would you mind taking a moment to rate my service? I'd really appreciate it!
